Obesity in Children

11-year-old sister Kylie Misher-Stenzler and her 9-year-old brother Colby are getting their annual dental check-up to keep their teeth healthy they brush twice a day with fluoride toothpaste.

"We have been lucky in that they haven't had cavities thus far," says mother Shari Misher-Stenzler.

New guidelines from the American Dental Association say children should begin using toothpaste with fluoride as soon as they get their first tooth to help fight cavities. For kids under 3, parents should use just a smear. For children 3 to 6, a pea-sized amount is suggested. (graphic?)

"Not having the fluoride you would be more susceptible to decay as the teeth wear down and lose their certain minerals."

Previous guidelines recommended fluoride toothpaste only after age 2.

The American Dental Association says early prevention is important because about 1 in 4 children have cavities by the time they enter kindergarten.

But, dentist Mark Hochberg says use only small amounts of fluoride because when swallowed it can discolor permanent teeth. "As they are forming chronically ingesting fluoride causes flurosis."

This mom says it's all about being diligent. "It's pretty standard and old school, brushing their teeth, you know, routinely," says Misher-Stenzler.

Experts agree, daily brushing and flossing along with regular checkups are the best way to keep your children cavity-free.

Dentists say parents should also be diligent about getting their children to spit after brushing.
